Exactly. It's roughly $36,500,000 per mile of track with Mark monorail systems. I'm basing this off of an estimate of $25,000,000 per mile for Las Vegas' 1995 refurbished Mark system, simply adjusting the price for inflation. It's possible that in the last 15 years that there have been technological advances that would bring this cost down, but moving too far from the Mark-based monorail system would either complicate the monorail network or require rebuilding the current system. I don't know what a monorail train costs, and expanding the system to the other parks and resorts would probably require quite a few new trains, and it wouldn't hurt to replace the current trains.
